We certainly didn’t create the Numb3rs TV show, but some people at our company had a lot of fun providing math for each episode and the website about all that is still up: http://numb3rs.wolfram.com/ I personally haven’t done as much with Hollywood as I might because I find the high noise-to-signal ratio that tends to exist there very difficult to deal with. However, I had a nice experience helping a little (with one of my kids) recently on a movie project that hopefully will come out this year. (Of course, our technology gets used a lot in Hollywood: a nice recent example which takes us back to your gravitational wave question is https://www.wolfram.com/mathematica/customer-stories/academy-award-visuals-mathematica-wolfram-language.en.html)
